Evidence? I'm curious, mainly because I always hear about the Rust Belt and how it's been screwed over by outsourcing.
If you want to bring back the rust belt, you'll probably need to start a large war in Europe and Asia...
The rustbelt is caused by their inability to compete with the better quality Japanese cars (and Japanese salaries are higher than in the rustbelt, you can't make the cheap labour for that).
You can talk about the theoretical upsides to global free trade all you want. I'm a believer. But 2 billion people jumped into the labor pool and the reality in the US is that they made a wave that drowned a lot of people. Real wages are depressed. That's not to say there's any real alternative to full open participation in the global market, but your free-market cheer and pom-poms don't capture the full reality from a US worker perspective.
if you want to attack free markets, why not go further and advocate barriers on inter-state commerce within the US.
